YES(O(1),O(n^1))

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

Strict Trs: { h(f(x, y)) -> f(y, f(h(h(x)), a())) }
Obligation:
  innermost runtime complexity
Answer:
  YES(O(1),O(n^1))

We add the following dependency tuples:

Strict DPs: { h^#(f(x, y)) -> c_1(h^#(h(x)), h^#(x)) }

and mark the set of starting terms.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

Strict DPs: { h^#(f(x, y)) -> c_1(h^#(h(x)), h^#(x)) }
Weak Trs: { h(f(x, y)) -> f(y, f(h(h(x)), a())) }
Obligation:
  innermost runtime complexity
Answer:
  YES(O(1),O(n^1))

We use the processor 'matrix interpretation of dimension 2' to
orient following rules strictly.

DPs:
  { 1: h^#(f(x, y)) -> c_1(h^#(h(x)), h^#(x)) }
Trs: { h(f(x, y)) -> f(y, f(h(h(x)), a())) }

Sub-proof:
----------
  The following argument positions are usable:
    Uargs(c_1) = {1, 2}
  
  TcT has computed the following constructor-based matrix
  interpretation satisfying not(EDA) and not(IDA(1)).
  
          [h](x1) = [0 4] x1 + [0]           
                    [1 0]      [0]           
                                             
      [f](x1, x2) = [0 0] x1 + [1 1] x2 + [1]
                    [1 1]      [0 0]      [1]
                                             
              [a] = [0]                      
                    [0]                      
                                             
        [h^#](x1) = [0 4] x1 + [0]           
                    [0 0]      [0]           
                                             
    [c_1](x1, x2) = [1 0] x1 + [1 0] x2 + [1]
                    [0 0]      [0 0]      [0]
  
  The following symbols are considered usable
  
    {h, h^#}
  
  The order satisfies the following ordering constraints:
  
      [h(f(x, y))] = [4 4] x + [0 0] y + [4] 
                     [0 0]     [1 1]     [1] 
                   > [4 4] x + [0 0] y + [3] 
                     [0 0]     [1 1]     [1] 
                   = [f(y, f(h(h(x)), a()))] 
                                             
    [h^#(f(x, y))] = [4 4] x + [4]           
                     [0 0]     [0]           
                   > [4 4] x + [1]           
                     [0 0]     [0]           
                   = [c_1(h^#(h(x)), h^#(x))]
                                             

The strictly oriented rules are moved into the weak component.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).

Weak DPs: { h^#(f(x, y)) -> c_1(h^#(h(x)), h^#(x)) }
Weak Trs: { h(f(x, y)) -> f(y, f(h(h(x)), a())) }
Obligation:
  innermost runtime complexity
Answer:
  YES(O(1),O(1))

The following weak DPs constitute a sub-graph of the DG that is
closed under successors. The DPs are removed.

{ h^#(f(x, y)) -> c_1(h^#(h(x)), h^#(x)) }

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).

Weak Trs: { h(f(x, y)) -> f(y, f(h(h(x)), a())) }
Obligation:
  innermost runtime complexity
Answer:
  YES(O(1),O(1))

No rule is usable, rules are removed from the input problem.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).

Rules: Empty
Obligation:
  innermost runtime complexity
Answer:
  YES(O(1),O(1))

Empty rules are trivially bounded

Hurray, we answered YES(O(1),O(n^1))
